Hrm, yes that is an interesting thought. I imagine that many PWM 
devices have similar constraints, so perhaps that would be best 
handled generically in the pwm core? Maybe as new optional get_*() 
ops, a modification to the config() op to add output params, or just 
updating new fields in the struct pwm directly?
